Hi Richard, Creating the 3.3V is no problem but should it only go to the spare pin > on the power connector or also go to the 18F4550 so selectable 5V or > 3.3V power on the 18f4550 ?
Yes, let's put 3.3V on the spare pin of power connector (I think it's where it was originally designed to). As for powering 18F4550, I guess 5V is enough. I have a LF version which can go far lower than 3.3V, but it's another topic and quite advanced feature. > > Or maybe all the 5V on the main board (after the fuse) selectable > between 5V and 3.3V and only let 5V go to the serial connector. > Is it complicated to do this ? Does it worth it ? Can it be postpone on a next version without much changes if it becomes very important ? And maybe some serial connectors can use 3.3V. too I guess there are many options we can't cover. For now, we can stay on 3.3V on spare pin, for shields, and let the PIC be powered with 5V > > > My mistake, I measured wrong... > > > How is that possible, in paris you have the exact Meter in Bureau > International des Poids et Mesures in Parijs thus so close to your > home :-). Yes, but probably my eyes weren't so close to my orbits...
